nmr_identify_regions_urine: NMR peak identification (urine samples)

In sipss/AlpsNMR: Automated spectraL Processing System for NMR

NMR peak identification (urine samples)

Description

Identify given regions and return a data frame with plausible assignations in human urine samples. The data frame contains the column "Bouatra_2013" showing if the proposed metabolite was reported in this publication as regular urinary metabolite.

Usage

nmr_identify_regions_urine(
  ppm_to_assign,
  num_proposed_compounds = 5,
  verbose = FALSE
)

Arguments

ppm_to_assign	A vector with the ppm regions to assign
num_proposed_compounds	set the number of proposed metabolites sorted by the number times reported in the HMDB: HMDB_urine.
verbose	Logical value. Set it to TRUE to print additional information

Value

a data frame with plausible assignations.
